Write a C++ program to illustrate the static variable functionality using the sum of a Fibonacci series as an example.

Program Code:

#include<iostream.h>

class item

{

public:

static int sum;

void fibo(int f,int s)

{

if(s>100)

cout<<"Sum="<<sum<<endl;

else

{

sum+=s;

fibo(s,f+s);

}

}

};

int item::sum;

int main()

{

item a;

a.sum=1;

a.fibo(1,1);

return 0;

}
